Stroke can damage sensory and motor nerve transmission pathways， causing limb dysfunction in patients. Short latency somatosensory evoked potentials （SLSEP） can objectively assess the sensory and motor dysfunction caused by stroke from a neurophysiological perspective in the early stage， supplementing the deficiency of imaging and rating scales， and has important clinical significance for predicting patient functional outcomes. This paper reviews the evaluation of limb function and prognosis in stroke patients using SLSEP， providing a basis for clinical practice.
